Jack didn't even give Martina a chance to speak at this point because he understood that Elizabeth in front of him was no simple person.
Elizabeth was deliberately setting traps for Martina, and no matter what Martina said, it would be easy for others to misunderstand her.
This further intensified Jack's dissatisfaction with Elizabeth. If it weren't for the fact that she was Benjamin's birth mother, he might have lost his patience with her long ago. Honestly, he believed he had shown remarkable restraint with Elizabeth all these years. Despite her numerous behaviors that harmed the family in secret, he had kept his silence. He had done this mainly because she had given birth to such an outstanding son.
